What I do is cut a length of tissue that will give me 2-3 wraps for a light
tube and 5-6 wraps or more for a heavy tube. Cut the tissue longer than you
want the tube, and then you can cut multiple tubes from the same wrapping. I
use a mandrel that is either exactly the size of the post to be inserted, or
slightly undersized. Make the tubes before you make the posts, that way you
can fit the posts precisely to the finished tube.
I use duco thinned to 60% with acetone. Apply glue mixture liberally to the
tissue, i use my finger to smooth the glue and let it soak into the tissue.
Then roll the tissue around the mandrel. Here is my trick. Let the tissue
overhang about 1/2 inch from the mandrel. This will allow you to poke a pin
through the tube to allow air to release as you pull the tube off the
mandrel with needle nose pliers. If you do not poke an air release hole,
when you pull the tube off it will collapse, usually the lighter tubes do
this. You want to remove the tube from the mandrel BEFORE the glue dries.
Best of luck,
Ben Saks
